Colorado . EIN / Federal Tax ID

An Employer Identification Number is your business's federal tax ID. Colorado entities need one to open a business bank account, hire employees, file federal taxes, and apply for most business credit. The IRS issues it free. File.Business handles the application end-to-end.

Frequently asked

Colorado EIN questions.

Does the Colorado Secretary of State issue my EIN?

No, and this is a common mix-up: your EIN comes from the IRS, a federal agency, not the Colorado Secretary of State, which handles your state entity registration. You need both, the Colorado filing to create the entity and the federal EIN to bank and file taxes. We obtain the EIN and complete the Colorado registration together so nothing is missing.

Do I need my Colorado entity before I get an EIN?

Usually yes: you generally form the entity with the Colorado Secretary of State first, then apply for the EIN in the entity's exact legal name, so the IRS record matches the Colorado record. Applying out of order can create a name mismatch. We sequence the Colorado filing and the EIN so they line up cleanly.

Is an EIN free from the IRS?

Yes, the IRS does not charge for an EIN, and anyone claiming the government fee for it is misleading you. Our value is getting it right and fast, especially for founders without a Social Security number, and coordinating it with your Colorado filing. We never imply the EIN itself costs a government fee.

Can a non-US founder get an EIN for a Colorado entity?

Yes: you do not need an SSN to obtain an EIN for a Colorado LLC or corporation; the IRS has a process for foreign responsible parties, though it takes longer than the online route. It is a common step for international owners. We obtain the EIN for your Colorado entity even without an SSN so you can bank and operate.

What do I use my EIN for after forming in Colorado?

To open a business bank account, hire employees, file federal and often Colorado taxes, and identify the business instead of your SSN. It is the entity's federal tax ID. We make sure your Colorado entity has its EIN in hand so banking and payroll are not held up after formation. Link llc-bank-account? no hub. Link get-an-ein.

Does each Colorado entity need its own EIN?

Generally yes: each separate LLC or corporation you register with Colorado should have its own EIN, since sharing one across entities blurs the tax and liability lines. A single-member LLC with no employees can sometimes use the owner's SSN, but a distinct EIN is cleaner. We obtain an EIN per Colorado entity so each stands on its own. Link holding-company.

Do I need a separate Colorado state tax ID too?

Often, if you have employees or collect sales tax: the federal EIN is one number, and Colorado issues its own state tax or employer account number when you register for payroll or sales tax. They are different IDs for different filings. We obtain the EIN and complete the Colorado state tax registrations you actually need. Link sales-tax-registration.

What if my EIN information does not match my Colorado filing?

A mismatch between the name on the EIN and the Colorado Secretary of State record can cause bank and tax problems, so the two should agree exactly. It usually happens when the EIN is obtained before or separately from the entity. We align the Colorado filing and the EIN so the federal and state records match.

Can File.Business get my EIN with my Colorado formation?

Yes. We form or register your entity with the Colorado Secretary of State and obtain the federal EIN in the same process, including for non-US founders without an SSN, so you leave with both the state registration and the federal tax ID rather than chasing the IRS separately.
